Disclosed herein is a flexible single piece active element for use in connection with aspirating electrosurgical ablators, particularly those configured for bulk tissue vaporization. The active electrode elements of the present invention provide a simple construction suitable for use with a wide array of electrosurgical components and adjustable to wide range of angled positions to permit access to a variety of tissues, in an array of diverse environments and address a host of ablation needs. Additionally, the novel geometry and positioning of both ablation surface and aspiration ports permit aspiration flow to remove primarily waste heat rather than process heat, to thereby improve vaporization efficiency and reduce procedure time. Thus, active electrodes and ablation devices of the present invention maximize efficiency and adaptability while minimizing manufacturing cost and device profile.

The present disclosure is directed to a surgical device and method of using the same. The surgical device includes a proximal ring, a distal ring, wherein the distal ring is operably connected to the proximal ring with a sleeve, the sleeve extending about a circumference of the proximal ring and a circumference of the distal ring, a film, a distal end of the film attached to a portion of the distal ring, wherein the film is configured to extend past the sleeve and past the distal ring, and wherein a proximal portion of the film comprises an opening and a channel and a draw string extending through the channel and exposed to an exterior of the device through the opening. 1. A surgical device comprising:a proximal ring;a distal ring, wherein the distal ring is operably connected to the proximal ring with a sleeve, the sleeve extending about a circumference of the proximal ring and a circumference of the distal ring;a film, a distal end of the film attached to a portion of the distal ring, wherein the film is configured to extend past the sleeve and past the distal ring, and wherein a proximal portion of the film comprises an opening and a channel; anda draw string extending through the channel and exposed to an exterior of the device through the opening.2. The surgical device of claim 1 , wherein the film comprises an interior surface and an exterior surface claim 1 , and wherein the interior surface is substantially sterile.3. A method of using a surgical device claim 1 , the method comprising the steps of:deforming a distal ring of the surgical device, the surgical device comprising a proximal ring, the distal ring, wherein the distal ring is operably connected to the proximal ring with a sleeve, the sleeve extending about a circumference of the proximal ring and a circumference of the distal ring, a film, a distal end of the film attached to a portion of the distal ring, wherein the film is configured to extend past the sleeve and past the distal ring, and wherein ...

A handheld device includes an electronic instrument and a capacitive power supply for storing and delivering power to the electronic instrument. The capacitive power supply includes at least one capacitor, and an electronic circuit operable to boost a voltage from the capacitor to a higher voltage for use by the electronic instrument. The capacitive power supply can be rapidly recharged. Some configurations include an accelerometer which permits the handheld device to detect movement and perform various operations responsive to detected movement. A dual charging station is also disclosed.
